WINDOW-SCREEN.

Specification of Letters Eatent.

Patented Jan. so, 1917.

Application filed December 1, 1915. Serial No. 64,538.

To all whom it may concern:

Be it known that 1, CHARLES -W. Hmoncmrrn, a citizen of the United States, residing at 426, ater street, in the city of Lawrence, Massachusetts. have invented an Improvement in Vindow-Screens, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts. i

This invention relates to window screens of a demountable type adapted to be pivotally secured in position in a window frame.

An object of this invention is to provide a window screen with means whereby it may adjust itself to inequalities and inaccuracies in window frames and present an insecttight closure.

A further object is to provide a screen with means by which it may be readily p0- sitioned in a window frame and removed therefrom by one on the inside. of the room and with means affording access, when the screen is closed, to the manipulation of the usual window shutters and whereby interference of shutter fasteners on a window sill with the screen movement is avoided.

other objects of the invention will more fully appear from the following description and accompanying drawings and will be pointed out in the annexed claims.

In the drawings, wherein a selected embodiment of this invention has been illustrated, Figure 1 is a view in elevation of the screen in closed position and looking outward through the window frame; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. 1.

The window frame 1 is shown as of the usual construction and has this novel screen applied thereto. The screen comprises the main frame 2, preferably of wood. to which is secured the wire netting 3. This netting in this construction of the screen, is preferably stretched across the screen frame 2 and the perimetrical portions of the netting are secured to the frame by means of an auxiliary frame. This auxiliary frame also functions as a main frame reinforcing medium and is composed of the uprights 4 and 5 and the top and bottom bars 6. Preferably. though it is not necessary here to be shown, the auxiliary frame has a bar similarly securing the netting to and reinforcing the cross bar 7 of the screen frame 1. These members of the auxiliary frame are,

combining tioned. on the screen inequalities due to wearer warm in this embodiment preferably secured to the main frame by screws 8 in order that they may be readily demountable when it is desired to remove the netting for replacement or repair. I The members of the auxiliary frame are preferably formed of thin steel maximum rigidity, durability, and economy of space. The wire netting 3 is thus held in taut position on the screen frame.

In order that this novel screen may be opened and closed as desired, there is provided means bywhich it is piyotally positioned in a window frame. ln this selected embodiment this is accomplished by means of a plurality of hinges 9. One member of each of the hinges 9 is secured in a recess provided therefor in the outside surface of the screen frame. These countersunk hinge members are thus covered and reinforced by the upright 5 of the auxiliary frame. The other members of the hinges are each secured, preferably by rivets 10, to the angle strip 11. This angle strip 11, in this embodiment, is made of thin steel and is detachably secured at its inner face by the screws 12 to one of the opposed inner faces of the window frame 1. It is apparent that by the use of such organization, the window screen may be completely assembled and thereafter placed in a window frame as a self contained structure and secured in position by turning down the screws 12 into the frame.

It is a matter of common knowledge that window frames are often inaccurately constructed or. through action of time and the elements, 'become warped and distorted. Hence, it is preferable to provide this screen with means adapted to compensate for such inequalities. Obviously, the hinged side of the screen through the angle strip construction will accurately close that side. The strips screwed to the top bar 6 and the upright 4 of the auxiliary frame are so posiframe, or may be of such width, as to project beyond the respective frame portions to which they are secured. Therefore, when the screen is in closed position, these strips overlap the adjacent portions of the window frame. Thus, the screen frame is assured of an insecttight closure on these three sides whatever may be the condition of the window frame, whether due to inaccuracies of construction,

' g or other defects. In this novel structure, the portions of the auxiliary frame and the angle strip are the only portions which normally project beyond the vertical plane of the outside of the window frame and these portions being of thin steel themselves will demand a minimum of space. Hence, interference with the closing of the usual window shutters or blinds is avoided.

Heretofore, when screens of this general type were in closed position, it has been necessary to open the whole screen in order to adjust or otherwise manipulate the window shutters. Further, holes, with their attendant disadvantages, have of necessity been provided in the screen frames at the bottom in order to accommodate the usual shutter fasteners. Herein is provided a novel means not only for permitting manipulation of window shutters when the screen is closed but which also affords a screen base'adapted to adjust itself to any inequality of the window sill surface and which avoids interference with such shutter fasteners. The screen netting, in this embodiment, preferably does not extend the length of the screen frame uprights 4 and 5, it terminating at the bottom bar 6. The slide 13 functions as a closure for this lower portion of the main screen frame. This slide is preferably provided with a mounting on the inner side of the screen frame. It results that there is afforded by this construction a space equal to, and pre sented immediately beneath, the bottom wooden bar 6 of the screen so that interference with the usual shutter or blind fasteners by the screen or slide is avoided. A guideway is formed in this selected embodiment for the reciprocation of the slide. For this purpose the opposed faces of the inside of the screen frame are channeled a short distance upward from the lower ends. And, to these faces are secured the guide strips 14, which function to form in conjunction with the channels a guideway for the slide 13. The slide, consists of a thin sheet of metal, has a lap 15 formed by turning a small portion of the bottom at right angles. This lap is adapted, when the screen is in normal closed position, to rest upon the sill of a window frame. The top of the slide has a similar turned over portion or lap 16 which functions to rest upon the upper surface of the bottom bar 6 of the screen frame and thus to prevent the escape of the slide from the guideway when the screen is swung open. A simple means of raising the slide is afforded by the upstanding tabs 17 which are formed by cutting the metal of the slide prior to turning over the upper lap 16.

lVhile any suitable means of locking the window screen in closed position may be used, there is here shown a. simple form which preferably .a netting supported thereby,

consisting of a plurality of fingers 19 pivotally secured to the inside of the screen frame and adapted upon turning to engage the inwardly presented faces of the window frame. There are three such fingers 19 shown in Fig. 1. These fingers are preferably thin sheet metal shaped in the form disclosed and pivotally mounted upon the wooden frame 2 of the screen. The outer end of each finger is preferably tapered so that it may, upon turning, be pressed into the wood of the adjacent window frame portion and thereby lock the screen.

The chains 18 are in this embodiment secured to the main frame of the screen and afford a simple means for opening and closing the screen.

This novel window screen may be swung open so as to leave the whole window frame unobstructed thereby, as for example, when it is desired to wash the windows on the outside. When the screen is closed by the simple raising of the slide at the bottom of the screen, the blinds or shutters may be closed. And, due to the fact that the slide is positioned on the inside of the screen frame, interference by the slide with the usual shutter fasteners on the sill is avoided.

There is thus produced a durable, efficient, hinged window screen which is of relatively low construction cost, which is adapted to compensate to some degree for the inequalities of the window frame, is simple in operation and pleasing in appearance.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A window screen adapted to be positioned in a Window frame and having a main frame, a netting supported thereby, an auxiliary frame secured to the main frame and clamping the perimeter of the netting therebetween, window frame, hinges pivotally to secure the screen to the strip, and a slide positioned adjacent the lower portion of the screen and movable to permit the manipulation of shutters and to permit the opening and closing of the screen Without interference with shutter fasteners.

2. A window screen having a main frame, an auxiliary frame secured to the main frame and clamping the netting therebetween, an angle strip, hinges securedto the screen and to the strip, means for detachably securing said strip to one of the opposed faces of a window frame whereby said strip and screen may be installed as aself-containcd structure and after installation the screen may be opened and closed by pivoting on said hinges.

3. A window screen pivotally mounted in a window sash and having a frame, a

a strip secured to the netting supported thereby, a transverse frame member above the lower ends of the main frame, said netting terminating thereat, a slide vertically movable on the lower ends of the frame normally to form a closure conforming to the window frame sill and movable to afford access to the screen exterior, and means on the slide to retain the same in normal position upon the movement of screen about its pivot.

4. A. window screen pivotally mounted in a window sash and having a frame, a netting supported thereby, a transverse frame member above the lower ends of the frame, said netting terminating thereat, a slide vertically movable on the lower ends of the frame normally to form a closure for the space between the netting terminus and the lower ends of the frame, and movable to afford access to the screen exterior, a lap on said slide normally engaging said transverse member and thereby supported in nor- Copies of this patent may be obtained for mal position upon movement of the screen about its pivot.

5. A window screen pivotally mounted in a Window sash and having a frame, a netting supported thereby, a transverse frame member above the lower ends of the frame, said netting terminating slide vertically movable on the lower ends of the frame normally to form a closure for manipulated.

In testimony whereof I have signed my name to this specification.
